  • Page 21: Labelling

    The cabling specifications depend on the type of communication interface to be used. The QT50 has four threaded M20 holes for cable glands. When ordering it is important to consider factors like cable type and size, as the cable glands have a limited cable entry range.

  • Page 22: Storage

    Power consumption The power consumption varies depending on whether the actuator is in standby mode or is running, see Table 5: System performance parameters for QT50 actuators on page 17. Inrush current after loss of power might be high. It is therefore recommended to design the circuit in accordance with information given in chapter 7.1.
